Specification of Letters Patent. I Patented Apr; 11, 1922.

Application filed February 5, 1920. Serial No. 356,458.

T o'all whom it may concern: I Be it known that I, HARRY H. STEPHENS, a citizen of the United States, residing at Glen Rock, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Centrifugal Machines, of which the following is a specification.

My present invention relates to improvements in centrifugal machines, particularly of the type in which the rotating basket. is carried on a rigidly supported vertical shaft. One of the objects of my invention is to arrange the supports for such a basket in such a manner that there will be no possi .bilityof the lubricant" from thebearings for the shaft getting into the basket, and yet at the same time constructingthe machine so that it may be driven from above.

Another object of my invention is to pro vide such a machine with a construction which will permit the ready. removal of the basket from the machine, as will be necessary at times for purposes-of repair or the like.

With these and other objects in vi'e\v,-my

invention consists in the combinations and arrangements hereinafter more fully dc scribed and specifically pointed out in the claims. v

In the drawings. Figure l is a side elevation, partly in section. of one specific embodiment of my invention; Fig. 2 is a plan view of Fig. 1, and Fig. 3 is a. fragmentary side elevation, partly in section, of a modification embodying my invention. Like reference characters indicate like parts in the. several Views.

In the arrangement shown in Figs. 1 and 2 a circular frame 10 is provided with a central, tubular structure 11, in the upper and lower portions of which respectively are .arrangec bearings 12 and 13 for a vertical 4 power is available. I utilize an electric motorto drive a vertical driving shaft 18 which, in the form illustrated in Figs. 1 and 2, will become the .armature shaft. This shaft is mounted in suitable bearings in the usual manner, and the motor frame 19;which carries these hearings. is attached to a bracket 20. which in the form illustrated, is pivotally connected at 21 to the frame 10. 1-} rotatable screw passes'through a nut 23 attached to a bracket 24, connected to the bracket 20, the other end of the screw 22' being rotatably connected to a pivotally mounted member pivoted at 26 to the frame 10. Normally. bolts pass through the bracket 20 and through the frame 10 to hold the bracket 20 rigidly in position, but when these bolts are. removed a rotation of/the screw 22 will turn the bracket 20 on the pivot 21 and tbus'swing the motor 19 and its shaft 18 into a position which will permit the basket 17 to be moved upward vertically on the shaft 14 to be taken out of the frame .10;

vIn order to permit this ready removal, the

driving connections between the shaft 18 and the shaft 11 are arranged so that the shaft 18 may be swung out of its normal position without necessitating any care on the. part of the operator. To this end I preferably provide a centrifugal friction clutch which has a driving member 26 connected to the shaft 18. the driving member 26 being covered with some friction material such as.

leather. When the motor 18 is rotate d to start the machine into operation, the on gagement of the projections 27 with the members 28 causes the latter to rotate. and as the speed increases themembers 28 are thrown outwardly to produce a driving pres; siire between them and the cup 29 to rotate nism may be applied to the cup 29 to stop I the baskets rotation.

' With. the form 0f friction drive illus trated, it will beobvious that as the bracket 20 is swung on its pivot the projections 27 will pass freely out of the openings in the mem are 28 with which they engage. and

that similarly, when the motor is returned the basket. If desired. suitable brake mec'ha-' 1 vertical shaft, bearings for said to its normal position these projections may readily be engaged with the corresponding openings in the members 28.

If electric power is not available, then I may substitute for the motor drive for the driving shaft a belt drive, such an arrangement being illustrated in Fig.3. In this arrangement a driving pulley 30 is mounted on hearings on a shaft 31 which is rigidly mounted in a bracket 32. which in turn is connected to the bracket 20. On the bracket 20 is an idler pulley bracket 32,- which carries bearings forone or more idler pulleys 33, around which the driving belt passes, usually from a driving shaft above the machine. The projections 27 in the arrangement shown in Fig. 3 are formed directly on the driving pulley, and theaigrangement otherwise is the same as that described as being illustrated in Figs. 1 and 2.

Many features of my invention may be varied within wide limits without departing from the spirit thereof, and I therefore do not wish to be limited to the specific embodiment of my invention which I have used for purposes of illustration.
